NUT LOCK. Y

Application :filed August 29, 1925.-V Serial' No. 53,322.

To all fr/rom t may concern'.

lle it known that I, IVALTER THOMPSON, a citizen of the vUnited States,residing at Airdrie, in the Province of Alberta and Do- "minion otCanada, have invented certain new and useful Improvements in Nut Locks,of' which the following is a specification, reference being had to the,accompanying drawings.

rlhis inventionlrelates to certain improvements in nut locks and hasrelaticn'more particularly to a device of this general characterespecially designed and adapted for use in holdinpr against displacementthe nuts comprised in a rail joint, `and it is an object of theinvention to provide a device of this kind and a novel and improvedmeans whereby the same may be readily and conveniently applied inworking position.

Another object of the invention is to provide a novel and improveddevice of this general character consisting of a member adapted to bearranged alongside of ka fish plate and to engage the nuts associatedtherewith together with means engageable with the rail for maintainingthe device in applied position.

It is also an object of the invention to provide a novel and improveddevice of this general character which, after beingV arranged in appliedposition, is spiked or otherwise secured to the ties ofV a trackway tomaintain the device inl applied or working position.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved nut lockwhereby certaink important advantages are attained and the device ren-`dered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanvingdrawings,wherein Figure l is a fragment-ar)T view in elevation illustrating` nutlock constructed in accordance with an embodiment of my vinvention andin applied position;

Figure 2 is a view in top plan of the struc ture as illustrated inFigure i;

Figure 3 is a sectional view taken suhstantially on the lineS-.fi ofFigure l;

portion of the member or arm y perspective of my improved nut lockunapplied.

As disclosed in the accompanying drawings, R denotes the meeting ends ofrails with each side of which is associated in a well-known manner thefish plate l andwith which coact in a' conventional manner the holdingbolts 2 and nuts 3.

The purpose ofthe invention is to provide means for holding the nutsSagainst displacement and as herein set forth said device comprises anelongated plate 4 adapted to be disposed Valona the fish plate l, saidplate 4 being of' a length greater than the length of the plate l toextend beyond (ipposite ends thereof'.

Theopposite end portions of thek plate 4 at the lower margin thereof areprovided with the outstanding flanges 5 adapted to have close contactwith the adjacent base flanges 6 of the rails R. Each of the flanges 5is continued by an inwardly disposed curved or arcuate member or arm 8adapted to be disposed beneath a rail with its free end substantiallyiiush with the opposite side of the base of the .rail when the deviceisin applied position. The free end 8 is flattened, as at 9, and saidfiattenedportion 'is pro- 8" vided with a slot l0.

A 'U-shaped member l1 is adapted to straddle the flattened portion 9 andthe adjacent base fiange of the rail R, the lower or under arm a of saidmember 11 adjacent its outer end is providedfwith -a lug Or rib 12 whichengages within the slot 10 when said member ll is forced inwardly of therail R to working` position. p

As the member 1l is forced into applied position the curved arms ormembers 8 as they arecorrespondingly sprung inwardly toward the bot-tomof the rail will operate to maintain lthe plate 4 effectively in appliedposition. The flanges 5 are also continued by the wings 14 each of whichbeing adapted to contact with a tie from above and with which it isadapted to be operatively en gaged by a spike or the like to furthermaintain the locking device in working position.

The plate 4 has its lower marginal portion cut out to provide aplurality of open slots 15, the lower portion@ of each ofthe slots beingof' greater width than the upper portion, By this arrangement the plate4 may be caused to straddle the nuts 3 from above irrespective of theposition Q f the 'side faces Figure 4 isa view in oi' said nuts andWliereby such nuts 3 will be effectively locked against backwardmovement or displacement.

From the oregoing description it is thought to be Obvious that ay nutlock constructed in accordance With my invention is particularly Welladapted 'for use by reason of the convenience and facility withWhicli'it may be assembled and operated, and it will also be obviousthat my invention is susceptible. otI4 some change and modiicationWithout departing from-the principles and spirit thereot and `for thisreason l do not WisliL to be understood as limiting myself to theprecise arrangement and formation ot the several parts herein shown incarrying out my invention in practice eX- cept as hereinafter claimed.

I claim l. A nut lock for rail joints comprising an elongated plateprovided with open slots to receive the nuts when the plate is inapplied position, arms carried by the plate and extending below therails when tlie plate is I in applied position, eacli of said arms beingprovided ivitli a slot in its outer end portion, and a U-sliaped memberengageable with the outer end portion of each ot' said arms and theadjacent portion o't' a rail, said member being provided with a lugengaging within the. slot of the arm.

Z. A nut lock :tor rail `ioint-s comprising an elongated plate providedwith open slots to receive the nuts when the plate is in appliedposition, arms carried by the plate and extending` belon-v the railswhen the plate is in applied position, and a U-sliaped member engageablewith the outer end portion oit cach ot said arms and t-lie adjacentportion ot' a rail.

In testimony whereof I hereunto aiiix my si gnature. y
